Hi! I build Chrome extensions and open-source tools focused on ad tech infrastructure, developer productivity, and GitHub automation. My work centers around ads.txt, app-ads.txt, sellers.json ecosystems, and and programmatic ecosystem tools. Check out my extensions below — all of them are free, open-source, and designed to solve real problems I've encountered in my day-to-day work.
